Solution

The salt of Ammonia( $N H_{3}$ ) forms brown color by the reaction with Nessler's reagent. and the salt is Ammonium chloride( $N H_{4} C l$ ).
The reaction is,
$\underset{N e s s l e r s' s r e a g e n t}{K_{2} H g I_{4} (l)} + \underset{A m m o n i u m c h l o r i d e}{N H_{4} C l (s)} + \underset{P o t a s s i u m h y d r o x i d e}{4 K O H (l)} \to \underset{B r o w n p r e c i p i t a t e}{N H 2 - H g - O - H g - I (s)} + \underset{P o t a s s i u m i o d i d e}{K I (l)} + \underset{P o t a s s i u m i o d i d e}{K C l (l)} + H_{2} O (l)$
So, the salt is Ammonium chloride.
